JULIUS A. HEINZ, OF SPRINGFIELD, MASSACHUSETTS.

WASHER-GUTTER- SPECIFICATION forming part of Letters Patent No. 633,316,dated September 19, 1899. i Application filed December I, 1898. SerialNo. 697.998. (No model.)

To all whom, it may concern:

Be it known that I, JULIUS A. HEINZ, a citizen of the United States,residing at Springiield, in the county of'I-l'ampden and State ot'Massachusetts, have invented a new and usefuly Improvement `inTasha-Cutters, which improvement is fully setforth in the followingspecification and shown in the accompanying drawings.

My invention is a device for cuttinga number ot concentric washerssimultaneously out of leather or similar material as by means of a blowof a heavy ham-meror a stamp motion of a suitable operating-machine.

The object of the invention 4iis to provide a convenient-tool or-devicetoi be heldin the hand or inserted in amaehine for quickly 'forming atone action a plurality of washers, means being provided for convenientlyforcing out or discharging the formed` washers from the cutter.

Theinvention is hereinafterfullydescribed, andmore particularly pointedout in the claims. v

Referring to the drawings, Figure l is an elevation of the device whenmade inthe form of a hand-tool. Fig. 2 is an axial section ot' theheadof the device vtakenl on the dotted line 2 2 in Fig. 3, uncovering theA`interior parts, parts being shown in two positionsl by full and dottedlines. Fig. 3 is a lower end view seen as indicated by arrow 3` in Fig.2. Fig. 4 is an axial lsectiouot' parts laken on the dotted line 4 4 inFig. 3. Fig. 5 is a View of the hollow head of the device, seenas'indicatedby arrow Sin Fi'g. 2, the interior parts 'being omitted.'`Figi 6 is alplanf'of the upper face `ot" the cutter, indicated vby arrow6in Fig. 2. Fig. 7 -is an axial section of the cutter taken on theldotted line 7 7 in Fig. 6, the discharger being shown in two positionsby full and dotted lines.=- Fig. S shows a set of rings or washers las.produced-by the device. y Fig. l is drawn to a scale one-halt' that ofthe other iigures.

Referring to the drawings, A is the body of the device, it being of ironand formed with a hollow head B.

C is a circular steel cutter for forming the washers Ct b c, Fig. 8,from a sheet of material E, Fig. 4, of india-rubber, leather, or similarmaterial. The lower part ot' the cavity D in the head B is circular andformed to receive the cutter C, above which the cavity is reduced inwidth, as shown in Figs. 4 and 5. The upper surface of the cutter isstraight orfiat, as shown in Figs. 4 and 6, bearing directlyy againsttransverse surfaces or shoulders cl d of the head B, being held t0 placeby simple retaining-screws e e. The lower or working face of the cutteris formed with a series of circular concentric cutting edges l 2 3 4,Figs. 3, 4, and 7, separated by annular grooves or spaces h '1T 7c and acentral space l. 'lhesecutting edges have diameters according to thesizes ot' the washers required, each cutting edge serving to form oneedge ot' a washer.

'The device is shown as a hand-tool, and in using it it is placed withthe cutting edges against the sheet E ot material from which the'washers are to be cut and struck upon the upper end a blow with a heavyhammer. This drives .the cutter through the material, as shown in Fig.4, separating the washers from the original sheet and from each other,the` sheet resting. upon a block of wood or other vsuitable backingduring the operation. lVhen the cutter is thus driven through the sheetof material and the washers formed,

they sti-ck or hold in the grooves between the cutters from friction andrequire to be forced out ordischarged theret rom. To accomplish this, Iprovide a dischargerF, formed of a bar or head f, and a row ot tines orteeth rigid therein extending vertically down through circularopeuingsm, Figs. 3, 6, and 7, through the cutter C. The head f is transverse inthe head B and occupies the narrow part of the space Dabove the cutter,its position being dia'metrical in the head B. The holes m in the cutterare longitudinal and formed in a diametrical row, as shown in Fig. 6,the outer tinesg gfbeing in position t-o project downward into the space7L of the cutter at opposite sides. The next inn'er tines u n are inposition to project into the space z', the tines o 0 project-ing intothe space lo, and the tinep into the middle space Z, said tine p beingin the axis ot the cutter and the body A.

To operate the discharger, I employa transverse shaft G, provided with acam or eccentric H, Figs. 2 and 4, to bear upon the upper surface of thehead j'. An external handle I ICO ot any desirable form is secured toone projecting end ot' the shaft G, by means of which to operate thelatter. The discharger is adapted to move in longitudinal directions inthe head B, and if the parts are in the relative positions shown inFigs. 2, et, and 7 and the handle be turned the discharger will beforced downward, as indicated by dotted positions. rIhis will cause thelower fiat ends of the tines to encounter the various washers and throwthem out from the cutter, the lniddle tine p pushing out the centerpiece u. To hold the discharger normally upward out of the way of thewashers while being formed, two spiral lifting-springs fr i', Fig. 7,are employed, coiled around the tines o o in enlarged cavities s s,Figs. 6 and 7, in the upper side of the cutter C. When the discharger ispushed downward by the cam to force the washers out of the cutter, saiddischarger moves against the action of the lifting-springs yr 9'. Thesesprings hold the head fot the discharger normally up against theshoulders tt ot' the head B, as appears in Figs. 2 and 4. As shown inFig. 2, the cam H turns through less than a half-revolution to throw thewashers out of the cutter. The limit ofthe motion ol the discharger isbetween the shoulders tt above and the surface of the cutter C below,the proportion of the parts being such that the washers aredischargedbefore the headf encounters the cutter. Now the cam when downbeing in the position shown by the dotted circle, the springs rfrserveto force it back t0 its normal position without the aid of theattendant-that is to say, when the attendant has forced out the cutwashers in any given case 11e merely releases the handle, giving theparts up to the control of the springs, which serve to return all themoving parts to their normal positions.

For forming washers of different diameters-external andiutermaldifferentlyformed cutters are provided to place in the head B,dischargers of ditterently-arranged tines being provided when necessary.

Vhat I claim as my invention is- 1. A non-rotating washer-cutterconsisting of a body havinga hollow head, and a cutter in the hollow ofsaid head, the cutter being a single piece and formed with a series ofconcentric cutting edges each a continuous or unbroken circle,substantially as shown and described.

2. A device for cutting washers, consisting of a hollow body, and aremovable cutter in said body, in a single piece, formed with aseries ofcircular concentric cutting edges, and a discharger for the cutter,substantially as described.

3. A device of the kind described, consisting of a body formed with acavity, and aremovable cutter in said cavity, the cutter being in asingle piece and formed with concentric grooves and separate cuttingedges, and a dischargcr for said cutter, having tines to enter saidgrooves from above the cutter, and means for operating said discharger,substantially as described.

4. A washer-cutting device having a cavity, and a cutter in said cavity,the latter having a reduced part, and a discharger for the washersoccupying said reduced partot' the cavity, the discharger consisting ofa head and tines rigid therein and extending through openings in thecutter, and a cam in said cavity to actuate the discharger, and means tooperate the cam, substantially as and for the purpose specified.

5. A device of the kind described, having a body formed with a cavity, acutter in the cavity and a dscharger in said cavity above the cutter,the body having shoulders to engage the cutter, and other shoulders ttto control the discharger, there being springs in the cutter to actuatethe discharger and move it against the shoulders it, and means to movethe discharger against the spring, substantially as shown and described.

G. A device ot' the kind described, formed with a hollow head, and acutter therein having a diametrical row of longitudinal holes, and adischarger in said hollow head formed with a head-bar provided with aseries of tines occupying said holes in the cutter, and means to movesaid tines in longitudinal directions in said cutter, substantially asspecified.

7. A washer-cutter consisting of a hollow body and a cutter thereinrigid with the body, a discharger in the body, above the cutter, a camadapted to turn on an axis in the hollow body to actuate the discharger,and springs held by the cutter to control the discharger and the cam,substantially as shown and described.

In witness whereof I have hereunto set my hand, this 21st day ofNovember, 1898, in the presence of two subscribing witnesses.
